Genes affected
PLCD1 (HGNC:9060): (phospholipase C delta 1) This gene encodes a member of the phospholipase C family. Phospholipase C isozymes play critical roles in intracellular signal transduction by catalyzing the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) into the second messengers diacylglycerol (DAG) and inositol triphosphate (IP3). The encoded protein functions as a tumor suppressor in several types of cancer, and mutations in this gene are a cause of hereditary leukonychia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

Collection Method:clinical testing

The PLCD1 c.1720G>A variant is predicted to result in the amino acid substitution p.Ala574Thr. This variant has been reported in the heterozygous state to segregate with leukonychia in a family (Kiuru et al. 2011. PubMed ID: 21665001). Functional studies showed that this variant results in ~40% increased enzyme activity (rat ortholog p.Ala553Thr, Nomikos et al. 2016. PubMed ID: 27783455). This variant is reported in 0.10% of alleles in individuals of European (Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
